Class scala.collection.IterableOps.SizeCompareOps

final class SizeCompareOps extends AnyVal

Operations for comparing the size of a collection to a test value.

These operations are implemented in terms of sizeCompare(Int).

Value Members

def !=(size: Int): Boolean

Tests if the size of the collection is not equal to some value.

Annotations
@inline()

final def !=(arg0: Any): Boolean

Test two objects for inequality.

returns

true if !(this == that), false otherwise.

Definition Classes
Any

final def ##(): Int

Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

returns

a hash value consistent with ==

def <(size: Int): Boolean

Tests if the size of the collection is less than some value.

def <=(size: Int): Boolean

Tests if the size of the collection is less than or equal to some value.

Annotations

def ==(size: Int): Boolean

Tests if the size of the collection is equal to some value.

Annotations
@inline()

final def ==(arg0: Any): Boolean

Test two objects for equality. The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

returns

true if the receiver object is equivalent to the argument; false otherwise.

Definition Classes
Any

def >(size: Int): Boolean

Tests if the size of the collection is greater than some value.

Annotations

def >=(size: Int): Boolean

Tests if the size of the collection is greater than or equal to some value.

final def asInstanceOf[T0]: T0

Cast the receiver object to be of type T0.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

returns

the receiver object.

Definition Classes
Any
Exceptions thrown

ClassCastException if the receiver object is not an instance of the erasure of type T0.

def formatted(fmtstr: String): String

Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).

def getClass(): Class[_ <: AnyVal]

Returns the runtime class representation of the object.

returns

a class object corresponding to the runtime type of the receiver.

final def isInstanceOf[T0]: Boolean

Test whether the dynamic type of the receiver object is T0.

Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

returns

true if the receiver object is an instance of erasure of type T0; false otherwise.

def toString(): String

Returns a string representation of the object.

The default representation is platform dependent.

returns
